Elizabeth Taylor: Never-before-seen pictures

In 1948, Mark Kauffman captured the young actress and her home life. Here, she gazes into the distance while wearing an "All America" sweatshirt; the pin she wears belonged to Glenn Davis, a 1946 Heisman Trophy-winning athlete she was dating at the time.

Taylor appeared on the magazine's cover a record 14 times, starting when she was just 15 years old, and over the following decades many LIFE photographerscaptured the astonishingly beautiful movie star. But a magazine only has so many pages -- and several stunning images of the Hollywood icon never actually made it to print. As such, LIFE.com is now featuring an unpublished gallery of photos of Elizabeth Taylor from the magazine's archives.

In costume as Marc Antony and Cleopatra, Burton and Taylor share a look on the set. They were the Brad Pitt and Angelina Jolie of their day, two impossibly gorgeous movie stars whose controversial relationship fascinated the world. They would marry not once, but twice.

During a break in filming A Place in the Sun, Taylor chats with her costar Montgomery Clift on the Paramount lot. The two would remain close friends; she would even save his life in 1956, after he smashed his car into a telephone pole following a party at her house (Taylor removed his shattered teeth from his throat, and kept him from choking).
